I agree with you that MAC is hard to find a good color match. I've tried NC35, C3, C4, and C40 in Studio Fix and I still can't find a good match. I'm very olive to the point that I look a little green, and MAC is either too pink or too orange, it's hard to get an in-between color for me. Unfortunately I can't offer you any advice because I'm too broke to try anything else.
